MQDH cannot installing latest CLI

When attempting to use MQDH, after selecting my Release Channel, the 'Upload' button remains stuck on "Installing Latest CLI".

This issue persists even after several hours despite multiple attempts to reinstall and update MQDH to its most recent version( I think my network shall be fine if I can update my MQDH). 

By the way,  I tried utilizing the ovr-platform-util method but encountered another obstacle. Upon running the command line, I received the error message "[DEBUG] A network error occurred. The request will be retried."

Stuck at Upload now
